I think you have it backwards. Standardized testing was a liberal policy to promote egalitarianism and civil rights, and it was historically opposed by conservatives. Liberals persuaded conservatives that standardized testing was a Good Thing, but as with segregation, opposition to mixed-race relationships, and general race essentialism, leftists are copying right-most folks in opposing standardized testing. It's not "liberals appealing to conservatives".
